INCINERATOR.

Applioatonled September 20, 1922. Serial No. 589,476.

To .all to/wm t may cof/wem.'

Be it known that I, WILLIAM W. GUM- MrNcs, a citizen of the UnitedStates, residing at 15 Winter Street, Woburn, in the county of Middlesexand State of Massachusetts, have invented new and useful Improvements inIncinerators, which are fully set forth in the following specification.

This invention vrelates to certain improvements in incinerators and hasfor its objects to more perfectly and economically incinerate garbage orother refuse, either gaseous, solid or liquid and to destroy all theodors incident thereto.

Hitherto incinerators have been constructed using a. flame ofv eithercoal, oil or gas playing directly on the garbage or other material to beincinerated-or such incinerators have had an added flame playing on thegases in certain combustion chambers indirectly or directly-or the gasesfrom the lirst distillation of the refuse have been conducted againthrough the fire before discharging them into the flue, but in each casethere has been no certainty of the odors being destroyed because it hasbeen possible to distill more gases than the flame could destroy or thetemperature could not be maintained at a sufficiently high point tobreak up the gases. Y

In order to attain the objects hereinbefore set forth, I provide anincinerator having embodied therein a container for the garbage or otherrefuse and directly above this container I provide a partition,preferably consisting of an arch with passages extending verticallytherethrough and also having passages extending therethrough at an angleto said vertical passages. Without departing from the spirit of myinvention, however, the partition may be made in the form of a diaphragmor checker brickwork. A burner is supplied for providing a comparativelysmall flame for distillation of the material to be incinerated andanother burner capable of providing a larger and more intense flame isprovided for breaking up the gases through the medium of the partitionhereinbefore referred to by rendering said partition incandescent and byso directing the flames that no more of the gas be distilled from thematerial by the lower flame than can be completely destroyed by theincandescent partition or arch, the result accomplished being that noneof the gases can escape into the flue of `conical shaped containerprovided with; slots 5 in its side walls. A grate 7 is provided beneaththe container 6.y The material to be incinerated is introduced into thecontainer 6 through a hopper 8 located` above and at one side of thecontainer 6. A flue 9 leads out ofthe topof the casing and beneath saidllue yand directly above the container 6 is a partition 10 constituting,

resent embodiment of my invention, y

in the an arc which is provided with vertically extendin passages 11passing therethrough and wit passages 12 extending therethrough at anangle to said verticaly passages.

The artition 10 is of approximately the same diameter as the upper endof the container 6, however, so that a large number of verticallyextending passages 11 can be provided in thepartition 10, and this isvery essential in order that the gases arising from the material beingincinerated shall'be thoroughly broken upv and be brought into contactWith the large area of the incandescent material of said partition.

A. burner 13 provides heat for incinerating the contents of thecontainer 6 and another and separate burner .14 provides heat for thepartition 10. Openings 15 and 16 in the side walls 2 of the casing areprovided for the flames from the burners 13 and 11i respectively to passthrough, for respectively heating the material in the container and forconsuming the gases which arise therefrom and contact with the partition10.

The burner 14 is positioned to direct` flames againstthe partition 10and preferablyv into the passages 12 to heat the partition 10 to anincandescence sufhciently high to break upy and burn the gases from thematerial in the container.

The general operation of the incinerator is as follows The material tobe incinerated is inserted in the container 6 through the hopper 8.Flames from the burner 13 are then directed intense heat bytlamesfromthe gas burnerv 14 which pass into the arch 1() through thepassages 12. The arch is 'heated toan incandescence suiiicientlyhigh andis provided With a large number 'of passages to breal; up and burn thegases arising from the material in the container o. -All these gasesmust pass through the small passages ar openings 11 inthe arch andtherefore are brought into intimate contact with the incandescentsurfaces of the arch before they can escape through the Hue 9 to thechim-y ney or outer air.

It'will be understood thatl in carrying-my4v invention into practicaloperation the source ot heat may be gas, oil, coal orelectricity,although in the present embodiment of my invention I have illustrated-vthe gas burners 13 and 14 for supplying the heat.y

In operat ng the device of this invention, it will be understood thatthe heat derived from the burner 13 will be only sullicient` to distlllsuflicient gas, so that the intense heatI of the incandescent partitioncan destroy Aall oi the gases arising'trom the container, in order thatnone of saidgases may escape into the flue Without coming nto intimatecontact `with said incandescent partition, whereby any obnoxious odorsorunburned gases may'escape into the atmosphere.

l. An incinerator having, :in combination,` a container for material tobe'inc nerated, a burner to heat the material in said con'- tainer, apartition located `directly above said container and being of'approximately the same diameter and having "openingsv therein :for thepassage of gases therethrough and a second burner positioned out of thepassage for sad gases and adapted to direct tiames against 'saidpartition to f-heat the same whereby gases arising from the heatedmaterial in said container may be destroyed. n p

2. An incinerator having, in combination, a container for material to beinc nerated, a burner to heat the material in saidV container, apartition located above said containeivhaving vertically extendingopenings for the passage. o't` gases therethrough and having otheropenings extending there through at an angle to said first-namedopenings andV a second burner pos tioned out or" the passageffoi. saidgases and adaptedl to. direct'. Haines through saidl other openingswhereby gases arising from .the heated material in said container may bedestroyed.y

3. An incinerator having, in combination, a container for material to be`ncinerated, a flue leading out or' said incinerator, a hopper openingthrough the side wall of said incinerator', said -container locatedbeneath saidhopp'er, a burner to heat the material in said container, anarch located directly above said conta .ner and hopper and beneath saidflue and having openings for the passage otgases therethrough and asecond burner positioned out of the passage for said gases and .adaptedto directy 'Haines against' said larch to heat the same whereby gases.arising from. the heated material in saidcontainer may bedestroyed.

In testimony whereof I have signed my name to these specifications inthe presence of the subscribing Witnesses.
